Java development practice: Using Qiniu Cloud to implement the image upload function
Abstract:
With the rapid development of the Internet, the image upload function has become one of the basic needs of many websites and applications. This article will introduce how to use Qiniu cloud storage service to implement the image upload function in Java programs, and explain the implementation of each step in detail through code examples.
Keywords: Java development, Qiniu Cloud, image upload, code examples
import com.qiniu.storage.Configuration; import com.qiniu.storage.UploadManager; import com.qiniu.util.Auth; public class ImageUploader { // 七牛云存储的配置信息 private static final String ACCESS_KEY = "your-access-key"; private static final String SECRET_KEY = "your-secret-key"; private static final String BUCKET_NAME = "your-bucket-name"; public static void uploadImage(String localFilePath) { // 创建七牛云存储的配置对象 Configuration configuration = new Configuration(); // 创建七牛云存储的认证对象 Auth auth = Auth.create(ACCESS_KEY, SECRET_KEY); // 获取上传凭证 String uploadToken = auth.uploadToken(BUCKET_NAME); // 创建七牛云存储的上传管理器 UploadManager uploadManager = new UploadManager(configuration); try { // 调用上传方法将本地文件上传到七牛云 Response response = uploadManager.put(localFilePath, null, uploadToken); // 获取上传结果 DefaultPutRet putRet = new Gson().fromJson(response.bodyString(), DefaultPutRet.class); // 打印上传结果中的图片链接 System.out.println("Image URL: " + "http://" + BUCKET_NAME + ".qiniudn.com/" + putRet.key); } catch (QiniuException e) { e.printStackTrace(); } } }
In the code, you need to replace ACCESS_KEY, SECRET_KEY and BUCKET_NAME with your own Qiniu cloud storage account and space information. Then, you only need to call the uploadImage
method and pass in the local file path as a parameter to implement the image upload function.
